Types and Variants of MBX RF Connectors
a. Right Angle MMBX Plug Connectors
A popular variant is the right angle MMBX plug connector, such as the Fairview Microwave FMCN1020. This connector supports RG316 and RG174 coaxial cables, featuring:
50-ohm impedance.
Frequency range from DC to 3 GHz.
Crimp/solder attachment methods.
Gold-plated beryllium copper contacts with PTFE dielectric.
VSWR of 1.17:1.
This type is ideal for applications requiring space-saving cable routing with reliable RF performance.
b. Surface Mount Vertical MMBX Connectors
For PCB applications, surface mount vertical MMBX connectors provide compact, high-frequency connections directly on circuit boards. These connectors, available from suppliers like Fairview Microwave and Newark Electronics, support frequencies up to 12.4 GHz and feature gold-plated contacts for excellent conductivity and corrosion resistance.
c. MBX Adapters
MBX adapters enable transitions between MBX connectors and other RF connector types, such as SMA. Baierde’s MBX adapters are engineered for rugged reliability with threaded coupling and provide excellent shielding against EMI/RFI interference. They support frequencies up to 18 GHz and offer IP67 environmental protection, making them suitable for harsh environments.
